Green Onion Cultivation Guide in Afghanistan
Practical green onion production guide for Afghanistan: climate, soil, irrigation, stage-based nutrition, deficiencies, pests, diseases and harvest.
Introduction and importance
Green Onion is an important vegetable whose quality depends on healthy seed or transplants, uniform growth and timely harvest.
Suitable climate and soil
Suitable for cool weather and fertile well-drained soil. Test soil and water before planting.
Land preparation and planting
Use healthy seed or transplants at uniform density with airflow; match date, depth and population to variety and location.
